影响出行链构成的多因素分析

Analysis of Multifactors Influencing Trip Chain Buildup

摘要:

以影响出行链构成的各类因素为研究对象，依据已有的理论基础和实践经验，设计了涵盖众多影响出行链构成因素的调查问卷.利用结构方程建模中的验证性因子分析方法，逐步筛选出影响出行链各构成因素的全集.剔除影响微弱的因素后，量化了各构成因素对于出行链不同程度的影响.

Abstract:

This paper combines the extant literature and experiences to design a questionnaire to capture as many factors influencing trip chain,a common concept describing travel arrangement,as possible in order to completely understand what kinds of factors should be weighted in the policies.Then structure equation modeling technique is applied to finishing the confirmatory factor analysis by which those factors with significant impact are identified to make up of the factor set.Meantime the influence coefficients among the factors are computed based on the data samples.

Key words:trip chain; structure equation model; confirmatory factor analysis; latent variable
